I bought a trailer adapter for a 2001 venture van. the instructions say to plug it into a connector on the driver's side rear. There is no connector there. I've look and so have a number of other people. the adapter is from hidden hitch part no.118355. Cutting and splicing I can get turn signals and running lights but not brake lights. This is without connecting thered wire of the module. where would this go?

I fixed it by running a wire from the brake switch.
